I have been working in Change Management for the past 7 years and have ITIL V3 foundation certificate. Right now I am working as a Change Management Analyst. I want to learn more and establish myself as an expert in this field giving more time to it and learning new things.
I am not sure how to go about it? Should I be looking forward to take new certifications like ITIL Intermediate level or PMP? If so please do suggest on what all I should be taking.

There are a number of specialist courses that have been accredited, including a couple just on Change Management. They are worth a point or two in the overall scheme as well. I suggest you look at websites from EXIN, ISEB and APMG to find these, and then find out if they are being offered near you_________________Liz Gallacher,
